Lexium ILA — drive and motor in one 57 mm housing
The ILA2P572PC1A0 is a Schneider Electric Lexium integrated drive from the ILA family — an AC synchronous servo motor with the drive electronics co-located in the same housing rather than in a separate cabinet. It belongs to the Lexium integrated drives line and drops into a 57 mm motor flange footprint, which is the standard NEMA-style small-frame servo envelope for indexing tables, light conveyors and laboratory automation. The supply is single-phase on a DC bus rated 18–55.2 V, which puts it in the low-voltage motion class rather than the 230/400 V three-phase servo tier — drive sizing must respect that bus window or the integrated electronics will not start.
Torque, speed and current — what 0.78 N.m buys you
Nominal torque is 0.78 N.m with a peak stall of 1.62 N.m and nominal speed of 1600 rpm at 24 V rising to 3400 rpm at 48 V. On the 48 V rail you get more than double the speed headroom of the 24 V rail — for cycle-time-critical applications the bus voltage selection matters as much as the motor selection. Continuous current draw is 7 A with a peak of 8.5 A, which is the figure that determines whether the upstream 24 V or 48 V supply, fusing and wiring gauge are adequate — peak demand arrives during acceleration and must not starve the DC bus. Positioning accuracy is +/- 0.05° from the single-turn encoder feedback — tight enough for indexing and registration duty without pushing the cost of a multi-turn absolute encoder.
Shaft, flange and mechanical envelope
The motor flange is 57 mm with a centring collar depth of 1.6 mm and a 9 mm untapped shaft running 20 mm long. No second shaft and no gearbox — coupling selection and mounting bracket design are driven entirely by this 57 mm bolt circle. The body is 163.8 mm long and shock/vibration rated to 150 m/s² (1000 shocks) and 20 m/s² (10–500 Hz) per EN/IEC 60068-2, so it survives on machine frames with gear-head side loads as long as the coupling is misalignment-tolerant. Cooling is natural convection with no integrated fan — derating starts above the 1000 m altitude ceiling unless the datasheet's thermal curve is consulted for the specific duty cycle.
Holding brake, safety and protection
This variant ships without a holding brake, so a vertical axis that needs to hold position under gravity must use an external failsafe brake or a counterbalance — do not assume the ILA family always brakes itself. Onboard protection covers output short circuit, Safe Torque Off (STO) and output voltage overload, with the four signal lines configurable as input or output — STO simplifies the safety circuit on collaborative cells where a category-1 stop is acceptable.
Compliance, environment and service life
Marked CE and qualified to IEC 60072-1, EN 61800-3 (second environment), EN/IEC 50178, EN 50347 and IEC 61800-3 Ed 2 — the EN 61800-3 second-environment rating is the figure that decides whether it can sit on the industrial floor of a plant without extra EMC filtering on the line side.
